Students will model a BNL developed non-toxic technique for removal of toxic metals from soil. By using iron as a model for a toxic metal, students will quantify the amount of iron in a soil sample before and after removing the iron.

Inquiry

Performance Indicators

KI 1 Scientific Inquiry:“The central purpose of scientific inquiry is to develop explanations of natural phenomenon in a continuing, creative process.”KI 2 Scientific Inquiry:“Beyond the use of reasoning and consensus, scientific inquiry involves the testing of proposed explanations involving the use of conventional techniques and procedures and usually requiring considerable ingenuity.”KI 2, Mathematical Analysis:“Deductive and inductive reasoning are used to reach mathematical conclusions.”

M2.1 Mathematical Analysis:“Use deductive reasoning to construct and evaluate conjectures and arguments, recognizing that patterns and relationships in mathematics assist them in arriving at these conjectures and arguments.

Interpret a graph constructed from experimentally obtained data”

PI 3.1 Physical Setting:“Explain the properties of materials in terms of the arrangement and properties of the atoms that compose them.”PI 3.2 Physical Setting:“Use atomic and molecular models to explain common chemical reactions.”

Major Understandings

MU 3.1cc, dd Physical Setting:

“A compound is a substance composed of two or more different elements that are chemically combined in a fixed proportion. A chemical compound can be broken down by chemical means.”

“Compounds can be differentiated by their physical and chemical properties.”

MU 3.2 a, b Physical Setting:

“A physical change results in the rearrangement of existing particles in a substance. A chemical change results in the formation of different substances with changed properties.”

“Types of chemical reactions include synthesis, decomposition, single replacement and double replacement.”
